Panasonic GH5 II vs GH5S: A Hands-On Expert Comparison for Imaging Enthusiasts

Choosing the right camera for your creative vision can be daunting, especially when models come from the same family but have very different strengths. Today, we’re diving deep into Panasonic’s professional Micro Four Thirds mirrorless lineup with a thorough comparison between the Panasonic Lumix GH5 II and the Panasonic GH5S. Both well-regarded bodies, but tailored for distinct photographic and videographic needs.

Leveraging years of hands-on testing with hundreds of cameras, and running these through controlled lab and real-world shoots, we’ll break down the strengths, compromises, and best use cases for each model - backed by detailed specs, image samples, and performance insights.

Getting to Know These Cameras: Key Specs at a Glance

Immediately, you can see that while these are siblings in the Micro Four Thirds ecosystem, they differ significantly in their sensor resolution, stabilization, and video capabilities, which affects their ideal use cases.

Handling, Design & Ergonomics - Comfortable Professional Control

Both cameras share the classic SLR-style mirrorless body design common in Panasonic’s GH series with identical physical dimensions: 139mm width, 98mm height, and 87mm depth. Despite very similar footprints, the GH5 II is heavier by about 70g mainly due to the build enhancements and added image stabilization system.

Their control layouts are well thought out for professional use, featuring illuminated buttons, customizable dials, and a fully articulated touchscreen LCD for versatile shooting angles.

The GH5 II features a 3-inch 1.84M-dot touchscreen, offering responsive touch control and intuitive menu navigation. The GH5S has a slightly larger but lower-resolution 3.2-inch LCD at 1.62M dots. Both feature identical 3.68M-dot electronic viewfinders (EVF) with 100% coverage and 0.76x magnification, ensuring clear visibility for composition and focus.

The GH5 II’s inclusion of sensor-based 5-axis image stabilization adds noticeable handling flexibility, reducing motion blur handheld and aiding video smoothness - a feature missing in the GH5S.

For ergonomics enthusiasts, the marginally smaller GH5S and lighter weight make it easier to carry during long wildlife or travel shoots.

Sensors and Image Quality - The Sharp Divide

Let’s dig into the heart of the matter: sensor technology. Both cameras sport Micro Four Thirds-sized sensors, measuring about 17.3x13 mm, but their designs and resolutions diverge sharply.

Panasonic GH5 II: 20MP for Maximum Detail

• Resolution: 20MP, no optical low pass filter (OLPF/anti-aliasing filter)
• ISO Range: 200-25600 native, extendable down to ISO 100
• Color Depth & Dynamic Range: Scored 23.7 bits and 13.1 EV at base ISO in independent tests, representing excellent tonal gradation and shadow retention for the format.
• Image Stabilization: Crucially, its 5-axis in-body image stabilization (IBIS) effectively counters camera shake for stills and video.

In practice, these specs translate to crisp, clean images with excellent detail reproduction and vibrant, natural color. The higher resolution is a boon for landscape, portrait, and studio photography where cropping or large prints matter.

Panasonic GH5S: 10MP Low-Light Champion

• Resolution: 10MP, also no OLPF
• ISO Range: 160-51200 native, extendable to a stunning ISO 204800
• Sensor Design: The GH5S uses dual native ISO technology, optimizing signal readout for very clean performance at higher ISOs.
• Color Depth & Dynamic Range: Not officially tested by DxOMark, but real-world use confirms significantly improved noise control at high ISO compared to the GH5 II and most MFT cameras.

The GH5S’s large pixel pitch allows better light collection per photosite, dramatically reducing noise and enhancing dynamic range at elevated sensitivities. This is key in wildlife, event, and astrophotography where lighting can be challenging.

In testing, low light shots at ISO 6400 retain excellent color and detail in the GH5S versus more visible noise and detail drop in the GH5 II. But be prepared for much lower overall pixel count.

Autofocus System - Reliable But Different

Both cameras deploy contrast-detection autofocus with 225 focus points and subject tracking capabilities. Panasonic's continuous improvements allow:

• Face Detection AF on both (GH5 II adds Animal Eye AF)
• Customizable AF modes: single, continuous, tracking, multi-area, and center
• Touch AF support for quick subject acquisition on-screen

The newer GH5 II boasts animal eye detection, a real boon for pet or wildlife shooters wanting sharp eyes with less fuss. The autofocus systems are reliable and fast enough for general photography including portraits and street shooting.

However, neither camera uses hybrid phase-detection AF, meaning that in very fast sports or extremely low light you might see somewhat slower AF performance compared to cameras with dual pixel or phase AF sensors.

Burst Shooting & Buffer Performance

Both models capture at 12 fps continuous shooting, great for fast action capturing in wildlife and sports applications. Buffer depths remain adequate but not exceptional for extended bursts in RAW mode, with the GH5 II benefiting from faster UHS-II memory card support and USB 3.2.

Video Capabilities - Pro Video with Differing Strengths

If video recording is a core part of your creative workflow, both cameras offer professional-level specifications but with notable contrasts:

The GH5 II’s 6K Photo mode is a standout feature, allowing ultra-high-resolution frame grabs from video clips, ideal for event or wildlife photographers combining stills and movies.

Meanwhile, the GH5S is tailored for low-light video production with dual native ISOs and superb performance under dim lighting, despite lacking IBIS.

For run-and-gun vloggers or handheld shooters, GH5 II’s in-body stabilization and articulated screen give a practical advantage for smoother footage and framing flexibility.

Build Quality and Weather Resistance - Ready for Rugged Use

Both cameras share a robust construction with magnesium alloy chassis and weather sealing, designed to withstand dust and moisture in challenging outdoor environments.

Neither offers specific waterproofing, crush-, shock-, or freeze-proof guarantees, so take care with harsh conditions.

Battery, Connectivity, and Storage

Both cameras support dual card slots allowing overflow storage or backup recording - a must for professional reliability.

The GH5 II’s USB 3.2 supports faster offloading and tethered capture vs. the slightly older USB standard in the GH5S.
